A heron drawn the height of the person wearing it
A grey heron stands charcoal on pale grey, running from collar to hem, because the bird's whole shape is vertical and a chest-width rectangle would cut it down.

A grey heron, side-on, charcoal on pale grey. It runs the full height of the shirt, collar to hem. The neck is folded down into its shoulders, one leg lifted, a single yellow beak.
Not centred on the chest. The whole garment is the frame.
Why does the heron run collar to hem instead of sitting on the chest?
Because the bird is vertical, and a chest-width rectangle would have to bend that shape to fit it.
Most animals printed on a shirt are wider than they are tall, so a chest-sized rectangle suits them. A standing heron is the opposite: nearly all height, almost no width. Printing it at the size a normal design occupies would mean either shrinking it small enough to lose the bird's actual proportions, or cropping the legs off. Running it the length of the garment instead means the wearer's own height becomes the frame the design was drawn for — the opposite move from a face cropped in tight, where everything except one feature was cut away.
Why is the neck folded rather than stretched out?
Because a heron with its neck extended is a diagram, and one with its neck folded is a bird that's been standing there for a while.
An extended neck is how field guides show the species, because it's the pose that best displays the neck's length and the head's shape. Folded down into an S against the shoulders is what a heron actually does for most of the time anyone watches one: waiting, motionless, for something to swim close enough. The folded pose is less informative and more true to what the bird is usually doing.
What makes the standing pose read as patient rather than just static?
The lifted leg, mostly — a bird balanced on one leg reads as paused mid-action, not posed for a picture.
A heron standing flat on both legs could be resting or could be nothing in particular. One leg raised implies the other position it could be in, which is enough to suggest motion without showing any. The single yellow note at the beak does similar work in colour terms: one accent against an otherwise flat charcoal figure, placed exactly where the eye goes first anyway.
Who owns the rights to a heron?
Nobody. A species belongs to nobody, and a drawing built from reference or observation is the artist's own to print.
A specific photographer's specific photograph is the exception — if a design were traced from a named photograph rather than built from general reference, using that image as the basis is a permission worth having, the same as for any picture somebody else took.
Does the tall-and-narrow treatment suit other subjects, not just other birds?
Anything with the same long-legged, upright build takes to it well — egrets, cranes and storks all share the heron's basic proportions, and the same logic scales in the other direction too: antlers reaching both shoulders use width the way this heron uses height, both printed at the size the display or the posture actually needs.
The angler on a wide dawn river works the opposite way for the same water — a tiny figure in a wide frame rather than a tall one, because that scene is about the whole river, not one animal in it.
Doesn't a design that runs the full length of the shirt limit where it can go?
It's placed where it has to be, which is a real constraint, but it's the constraint the design is built around rather than fighting against.
A collar-to-hem print sits centred, running down the front, which rules out pairing it with a pocket print or a pattern anywhere else on the same garment. For a design whose entire argument is the wearer's height, that isn't really a limitation — it's the same choice as the size, made once.
Does it print well?
Yes — a single dominant colour with one small accent is a reliable combination on fabric.
Charcoal on pale grey holds sharp edges at full garment length without any gradient to go muddy. The yellow beak is the only place worth a second ink; everywhere else, flat charcoal carries the whole bird, legs and all, down to the hem.
How do I get one made?
Describe the bird at JustOG — the species, the pose, and how far down the shirt it should run. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.
Designs other people have published are in the shop.
One yellow beak, and the rest of the bird all the way down to the hem.
